Detailed Description

The utility model is further described below. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in the figures, the frame welding tool based on the intelligent flexible welding robot comprises a tool table 2 for placing a workpiece 1, wherein a positioning device and a deformation correcting device 3 which are matched with each other are arranged on the tool table 2, the deformation correcting device 3 comprises a first supporting column 31 and a first pressing device matched with the first supporting column 31, the first pressing device comprises a first driving device and a first pressing block 32 driven by the first driving device, and the first pressing block 32 and the first supporting column 31 are respectively positioned above and below the workpiece 1.

When the welding tool is used, a workpiece 1 is placed on the tool table 2, as shown in fig. 3, when a position A9 is welded, a position B10 of the side edge of the workpiece 1 is prone to tilting, and after the welding is completed, the workpiece is continuously clamped by adopting the matching use of the first pressing block 32 and the first supporting column 31, so that the position B is prevented from tilting.

Further, the height of the first support column 31 is lower than the height of the workpiece 1. When the flexible welding fixture is used, the first pressing block 32 presses the part B of the workpiece 1 down to the first supporting column 31, after the part A of the workpiece 1 is welded, the first pressing block 32 is lifted, the part B of the workpiece 1 slightly tilts, and the force which is just pressed down is offset, so that the workpiece 1 is guaranteed to be flat, and flexible welding is realized.

Furthermore, the tool table further comprises a limiting device 4 arranged on the tool table 2, wherein the limiting device 4 comprises a second driving device and a third driving device, the second driving device drives a first limiting block 41 to move, the third driving device drives a second limiting block 42 to move, and the moving directions of the first limiting block 41 and the second limiting block 42 are perpendicular to each other. That is, the first limiting block 41 and the second limiting block 42 respectively limit the workpiece 1 in two mutually perpendicular directions, so as to prevent the workpiece 1 from moving and improve the limiting effect, as shown in fig. 4, the first limiting block 41 moves in the left-right direction, and the second limiting block 42 moves in the up-down direction.

Furthermore, the first stopper 41 and the second stopper 42 are both C-shaped, and pass through the C-shaped first stopper 41 and the C-shaped second stopper 42. When the tool table 2 is turned over, the workpiece 1 does not fall off from the tool table 2.
